Abstract:
Hydraulic technology is widely applied in various fields of national economy, so the performance of hydraulic system directly influences all aspects of the economic benefits. The status of hydraulic oil is important for the working performance of hydraulic system.The pollution of hydraulic oil is a reason，which causes the fault of hydraulic system And it will cause the failure of system and loss of benefit. So it's very important that the fault of hydraulic system be diagnosed and treated. This paper introduces hydraulic oil pollution and the method of diagnosing and treating it.

Abstract:
Lots of hydraulic valves lose efficacy every year because of the complex mechanism of construction machinery, bad working conditions and changeable objects. These invalid hydraulic valves were melted down in the oven and then reused. However, the additional value of valves is wasted, and it will consume a lot of resources. The remanufacturing industry, which is becoming more and more mature, can solve this problem. The hydraulic valve can be remanufactured by recollection and using professional technology. Here is an introduction of failure modes and remanufacturing process of hydraulic valve, and also a deep analysis to the benefits of economy, resources and environment. It turned out that remanufacturing can restore the function of the invalid hydraulic valve and shorten the production cycle. It also can save costs by 55%, save resources by 85% and save material by 90%.

Abstract:
Food system and energy planners have given scant attention to the impacts on agrifood systems of a particular form of energy production—fracking—and its implications for planning and regulation. Impacts include those related to water availability and quality; land quality, use, and value; wildlife; labor costs; infrastructure and services; and the implications of boom and bust dynamics of these for the sustainability of agriculture and food systems. Planning is challenged by competing frames of economic and environmental benefits, lack of capacity, power imbalances, and sometimes state policy. This review maps research on these linkages, identifies elements of successful planning, and offers directions for future research.

Abstract:
Secondary tropical forests and coffee agroforestry systems contain fewer trees than native forests but can positively impact soil hydrological functions, such as water infiltration compared to the pasture land that they replace. However, for both land uses it remains in how far the soil hydraulic characteristics are comparable to that of native forest. Therefore, we investigated the saturated hydraulic conductivity (Ks) and some hydrophysical soil attributes in four land-use types: (i) a shade-grown coffee; (ii) a natural regenerated forest 15 years ago; (iii) a pasture; and (iv) a reference forest, in the municipality of La Jagua de Ibirico, César department, Colombia. We determined historical land use and conducted soil sampling, using the Beerkan method to determine the Ks values. We also measured canopy cover, vegetation height, diameter at breast height and total number of trees in the forest covers. Our results indicate that Ks values were similar for the coffee and the reference forest, reflecting the positive effect of trees on soil hydrological functioning in agroforestry systems. Our results suggest that 15 years of forest regeneration after land abandonment in Sub-Andean Forest, can improve the soil hydraulic attributes. Additionally, soil water repellency was observed for the reference forest soil.

Abstract:
The primary goal of low impact development (LID) is to capture urban stormwater runoff; however, multiple indirect benefits (environmental and socioeconomic benefits) also exist (e.g., improvements to human health and decreased air pollution). Identifying sites with the highest demand or need for LID ensures the maximization of all benefits. This is a spatial decision-making problem that has not been widely addressed in the literature and was the focus of this research. Previous research has focused on finding feasible sites for installing LID, whilst only considering insufficient criteria which represent the benefits of LID (either neglecting the hydrological and hydraulic benefits or indirect benefits). This research considered the hydrological and hydraulic, environmental, and socioeconomic benefits of LID to identify sites with the highest demand for LID. Specifically, a geospatial framework was proposed that uses publicly available data, hydrological-hydraulic principles, and a simple additive weighting (SAW) method within a hierarchical decision-making model. Three indices were developed to determine the LID demand: (1) hydrological-hydraulic index (HHI), (2) socioeconomic index (SEI), and (3) environmental index (ENI). The HHI was developed based on a heuristic model using hydrological-hydraulic principles and validated against the results of a physical model, the Hydrologic Engineering Center-Hydrologic Modeling System model (HEC-HMS). The other two indices were generated using the SAW hierarchical model and then incorporated into the HHI index to generate the LID demand index (LIDDI). The framework was applied to the City of Toronto, yielding results that are validated against historical flooding records.

Abstract:
Abstract. Trunk mains are high risk critical infrastructure where poor performance can impact on large numbers of customers. Both quantity (e.g. hydraulic capacity) and quality (e.g. discolouration) of trunk main performance are affected by asset deterioration in the form of particle accumulation at the pipe wall. Trunk main cleaning techniques are therefore desirable to remove such material. However, little is quantified regarding the efficacy of different maintenance interventions or longer-term changes following such cleaning. This paper presents an assessment of quantity and quality performance of a trunk main system pre, post and for 12 months following cleaning using pigging with ice slurry. Hydraulic calibration showed a 7 times roughness height reduction after ice slurry pigging, evidencing substantially improved hydraulic capacity and reduced headloss. Turbidity response due to carefully imposed shear stress increase remained significant after the cleaning intervention, showing that relatively loose material had not been fully removed from the pipe wall. Overall the results demonstrate that cleaning by pigging with ice slurry can be beneficial for quantity performance, but care and further assessment may be necessary to realise the full quality benefits.

Full text
Abstract:
This thesis presents work on a holistic approach for improving the overall design of solar cooling systems driven by solar thermal collectors. Newly developed methods for thermodynamic optimization of hydraulics and control were used to redesign an existing pilot plant. Measurements taken from the newly developed system show an 81% increase of the Solar Cooling Efficiency (SCEth) factor compared to the original pilot system. In addition to the improvements in system design, new efficiency factors for benchmarking solar cooling systems are presented. The Solar Supply Efficiency (SSEth) factor provides a means of quantifying the quality of solar thermal charging systems relative to the usable heat to drive the sorption process. The product of the SSEth with the already established COPth of the chiller, leads to the SCEth factor which, for the first time, provides a clear and concise benchmarking method for the overall design of solar cooling systems. Furthermore, the definition of a coefficient of performance, including irreversibilities from energy conversion (COPcon), enables a direct comparison of compression and sorption chiller technology. This new performance metric is applicable to all low-temperature heat-supply machines for direct comparison of different types or technologies. The achieved findings of this work led to an optimized generic design for solar cooling systems, which was successfully transferred to the market.

Abstract:
This paper presents the results of a study on the effectiveness of porous overlays on urban highways. Permeable Friction Course (PFC) is a layer of porous asphalt applied to the top of conventional asphalt highways at a thickness of around 50 mm. PFC is often installed for safety and noise benefits, and is being seen as an emerging technology for meeting environmental requirements for stormwater discharge. The first objective of the study was to determine the impact of porous asphalt on the quality of stormwater runoff on highways with a curb and gutter drainage system. The quality of highway stormwater runoff was monitored before and after the installation of PFC on an eight-lane divided highway in the Austin, Texas area for 2 years. Observed concentrations of total suspended solids from PFC are 92% lower than those in runoff from the conventional pavement. Concentration reductions are also observed for nitrate/nitrite and total amounts of phosphorus, copper, lead, and zinc. The data shows that the results with curb and gutter are consistent with past results where runoff sheet flowed onto vegetated shoulders. The effect of two different binder compositions is also compared, showing an increase in zinc when recycled rubber is used. The second objective focuses on the drainage capabilities of PFC. While porous overlays can reduce stormwater accumulation on roadways, capacity at high rainfall intensities is limited. Installing subgrade underdrains within PFC could further improve stormwater conveyance. This research attempts to model the hydraulic profile of runoff as it approaches an underdrain with varying flow rates and grades. The results could assist TxDOT in the sizing and configuration of drains based on rainfall intensity and roadway geometry.

Abstract:
abstract: Recent literature indicates potential benefits in microchannel cooling if an inlet orifice is used to suppress pressure oscillations that develop under two-phase conditions. This study investigates the costs and benefits of using an adjustable microchannel inlet orifice. The focus is on orifice effect during steady-state boiling and critical heat flux (CHF) in the channels using R134a in a pumped refrigerant loop (PRL). To change orifice size, a dam controlled with a micrometer was placed in front of 31 parallel microchannels. Each channel had a hydraulic diameter of 0.235 mm and a length of 1.33 cm. For steady state two-phase conditions, mass fluxes of 300 kg m-2 s-1 and 600 kg m-2 s-1were investigated. For orifice sizes with a hydraulic diameter to unrestricted hydraulic diameter (Dh:Dh,ur) ratio less than 35 percent, oscillations were reduced and wall temperatures fell up to 1.5 °C. Critical heat flux data were obtained for 7 orifice sizes with mass fluxes from 186 kg m-2 s-1 to 847 kg m-2 s-1. For all mass fluxes and inlet conditions tested, CHF values for a Dh:Dh,ur ratio of 1.8 percent became increasingly lower (up to 37 W cm-2 less) than those obtained with larger orifices. An optimum orifice size with Dh:Dh,ur of 35 percent emerged, offering up to 5 W cm-2 increase in CHF over unrestricted conditions at the highest mass flux tested, 847 kg m-2 s-1. These improvements in cooling ability with inlet orifices in place under both steady-state and impending CHF conditions are modest, leading to the conclusion that inlet orifices are only mildly effective at improving heat transfer coefficients. Stability of the PRL used for experimentation was also studied and improved. A vapor compression cycle's (VCC) proportional, integral, and derivative controller was found to adversely affect stability within the PRL and cause premature CHF. Replacing the VCC with an ice water heat sink maintained steady pumped loop system pressures and mass flow rates. The ice water heat sink was shown to have energy cost savings over the use of a directly coupled VCC for removing heat from the PRL.

Abstract:
abstract: The rate of urbanization has been impacted by global economic growth. A strong economy results in more people moving to already crowded urban centers to take advantage of increased employment opportunities often resulting in sprawling of the urban area. More natural land resources are being exploited to accommodate these anthropogenic activities. Subsequently, numerous natural land resources such as green areas or porous soil, which are less flood-prone and more permeable are being converted into buildings, parking lots, roads and underground utilities that are less permeable to stormwater runoff from rain events. With the diminishing of the natural landscape that can drain stormwater during a rainfall event, urban underground drainage systems are being designed and built to tackle the excess runoff resulting from urbanization. However, the construction of a drainage system is expensive and usually involves massive land excavations and tremendous environmental disturbances. The option for constructing an underground drainage system is even more difficult in dense urban environments due to the complicated underground environments, creating a need for low footprint solutions. This need has led to emerging opportunities for low impact development (LID) methods or green infrastructures, which are viewed as an environmentally friendly alternative for dealing with stormwater runoff. LID mimics the pre-development environment to retain the stormwater runoff through infiltration, retention, detention and evaporation. Despite a significant amount of prior research having been conducted to analyze the performance of runoff volume reduction and peak flow decrement of various green infrastructures, little is known about the economic benefits of using LID practices. This dissertation fills the gap in the knowledge regarding the life-cycle-cost effectiveness of green infrastructure in current urban developments. This study’s two research objectives are: (1) Develop a life cycle cost calculation template to analyze the cost benefits of using LID compared to the traditional drainage system (2) Quantify the cost benefits based on the real-world construction projects A thorough literature review led to the data collection of the hydrological benefits of using LIDs in conjunction with overviewing three real-world construction projects to quantify the cost benefits of LIDs.

Abstract:
An oil and gas extraction technique called hydraulic fracturing has been common in the United States for many decades. However, a recent change in this technique—the development of a specific fracturing or “fracking” practice called slickwater or slickwater fracturing—has turned the world of petroleum extraction on its head, opening up massive new deposits of oil and gas in the United States and around the world. This article uses the United States as a case study of the benefits and risks of fracturing and the legal frameworks that apply to this practice, exploring how the legal approach has been largely piecemeal and reactive. US states have been the primary regulatory bodies responsible for controlling risks, and their regulations vary substantially. The federal government also has regulated in limited areas, however—again in a largely reactive and patchwork manner.

Abstract:
The interest of those involved in hydroelectricity has been attracted by mini-hydro projects due to their minimal environmental impact and low installation cost. Besides, mini hydros can cooperate with an impressively wide extent of water-related infrastructure, offering a broad potential for investment. In the present chapter, the integrated solution of hydro implementation in water supply systems is presented. Thus, the benefits of a water-supply installation (with constant Q) are extended to energy production. However, defining the optimum operation of such a project is a complicated task, which may involve environmental, hydraulic, technical, and economical parameters. In the present chapter a novel approach is presented, the optimum management of mini hydros in a water supply system with the use of an optimization algorithm (i.e. Harmony Search Algorithm [HAS]). This approach is applied at a site in Northern Greece and is used as a case study of the present chapter.

Abstract:
<em>Abstract</em>.—Ecosystem restoration of the Mississippi River main stem has been ongoing since the early 1970s. After the passage of environmental laws in the late 1960s to the early 1970s, private citizens and state and federal natural resource agency managers began to seek programs and funding for restoration and conservation that eventually resulted in mitigation measures of adverse impacts. Environmental-type actions that include the Great River Environmental Action Team, the Avoid and Minimize program, the middle Mississippi River biological opinion, and the lower Mississippi River conservation plan and biological opinion originated from laws or legal action. The Upper Mississippi River Restoration, Navigation and Ecosystem Sustainability Program, Restoring America’s Greatest River, and Operation and Maintenance activities, which support system ecological restoration measures, are, to a large extent, done in a cooperative setting to improve the river for multiple benefits. This coalition of agencies and professions has resulted in the application of hundreds of different types of measures to restore form and function to the third largest river in the world. Over the years, dredging and disposal practices have improved in an effort to minimize the impacts from these activities. Lost floodplain islands have been replaced, backwater lakes and channel depths have been recovered, active river flow has been reintroduced to backwaters, and microhabitats for special concern species have been restored, all to recreate broad functional floodplain habitat. Wing-dike and side-channel closure structures have been shortened, notched, or removed to recover flow along the main-channel border and side channels, increasing hydraulic residence time and recovering valuable habitat along with restoring nutrient and sediment assimilation processes the floodplain provides. Field monitoring has shown positive responses from endangered and threatened species, migratory and resident aquatic and wildlife species, abiotic conditions like water quality, and increased use by humans enjoying the benefit of a restored river system. Collectively, this work is some of the most extensive large river restoration in the world, but it only represents a small contribution to what is necessary to maintain a diverse and resilient Mississippi River. The information provided in this chapter provides a basis for continuing restoration efforts that should become a routine part of Mississippi River management.

Abstract:
The issues associated with this study are both physical and intellectual, as are the factors in urban development. The correlation of known data from inscriptions (epigraphy), literary references (ancient history and more recent government and church documents), evidence from destroyed and rebuilt buildings (archaeology), and modern scientific and technical findings (several kinds of engineering and subfields of geology such as seismology and sedimentology) can give a more complete picture of each city’s development than does one kind of information alone. Most of the necessary site-specific studies, however, have not been done. Our problem parallels the study of global warming, where precise records of weather events have been kept for less than 200 years. Urban elements must be studied by experts in that building type and in social expression. Ramparts need more study by historians of warfare, theaters by scholars of drama and literature, stadia by those who study the history of sports, plumbing by hydraulic, civil, and fluids engineers, and temples by historians of comparative religion. Insights into institutional and political aspects of ancient studies and the historiography of all the disciplines involved in ancient studies would be both useful and fascinating (Kardulias 1994). The benefits and difficulties of interdisciplinary research are clearer now to us than when we started. In considering the physical setting and geological processes in the Mediterranean area, is description sufficient or should scholars strive for explanation, even if this involves theory building? “In much of art history and classical archaeology traditional practices have continued without explicit theoretical support” (McNally 1985; but cf. Preziosi 1989). The theorists of archaeology and urban history desire comprehensive and precise theories—even in the absence of enough data to make that possible. Some data may be rescued by followers of one discipline after being ignored or thrown out by followers of another. The awareness of theoretical difficulty is part of the increase in consciousness typical of the second half of the twentieth century when we began to question the nature of both knowledge and culture.

Abstract:
<em>Abstract</em>.—Substantial investment in the engineering of the Mississippi River and its tributaries over the past ~200 years by the U.S. federal government has resulted in its transformation into one of the most regulated and intensively managed river systems in the world. The regulation and management of the Mississippi River system for a select set of ecosystem services has provided substantial economic benefits to the United States. These economic benefits include the transportation of goods, the reduction of flood risk to floodplain communities and agricultural lands, securing or increasing water supply, and reliable energy production. However, these benefits have come with substantial externalities such as altered hydrology, altered river hydraulics, decreased sediment load, changes in the pattern of delta sedimentation, increased nutrient loads, reduced habitat diversity, decreased ecological diversity, and degraded water quality. In this chapter, the natural, management, and engineering histories of the Mississippi River are reviewed. The purpose of this review is to describe the evolution of river management for harnessing the current services the river provides and the environmental and social externalities resulting from the management actions. It is hoped this holistic review of the Mississippi River will assist in leading toward a more complete and integrated vision for the management of this coupled natural–human river system.

Abstract:
The operability and efficiency of critical pumping equipment is essential. A cost-effective tool that has proven valuable in predictive and preventive maintenance and in the avoidance of unscheduled pumping equipment outages is a comprehensive program of periodic hydraulic and mechanical performance audits. This paper explains how hydraulic and mechanical field testing can be conducted without interrupting plant operations using non-intrusive measurement equipment including: ultrasonic flow measurements, vibration signature analysis, and for electric motor driven pumps, power and dielectric condition analysis. Methods and requirements to conduct the audits will be discussed and a case study with cost benefit analysis is presented. Pumps are basically energy transfer devices. The energy of the pump driver, e.g. electric motor, steam or gas turbine, reciprocating engine, is transferred into the pumpage to move it through the system at sufficient pressure to overcome system losses and meet process requirements. It is the efficient transference of the applied energy that is a critical consideration in pump design and operation. Efficiency of operation is of interest to everyone. The pump designer is motivated to maximize pump efficiency to remain competitive given the increasing cost of energy. However, the designer must not get overly zealous in the quest for pumping efficiency sacrificing reliability and durability. The end-user wants the most efficient pump with longest mean time between repair (MTBR) intervals to both reduce operating cost and minimizing production losses. With the reasons for maximizing pumping efficiencies and longer MTBR intervals established, the value of periodic in situ performance testing or auditing becomes an increasingly valuable and cost effective predictive and preventative maintenance tool.

"Early Applications of Viscosifying Friction Reducers for Hydraulic Fracturing Operations in the Vaca Muerta Formation, Argentina." In SPE Hydraulic Fracturing Technology Conference and Exhibition.

Abstract:
Abstract Early hydraulic fracturing completions in the Vaca Muerta Formation in central Argentina have incorporated the use of conventional fluid systems, such as linear and crosslinked guar-based polymers. Within the past few years, however, the benefits of viscosifying friction reducers (VFR) have been demonstrated in the industry, predominantly within the United States. The objective of this project was to trial the VFR fluid technology in fracturing operations in this area for potential use for full field development. After studying the potential advantages of the VFR technology including cost savings, simplified operations and enhanced well production, a project was initiated to determine if those same benefits could be obtained. To accomplish this, studies were performed to ensure economic and technical justification through a stepwise process of laboratory testing, logistical and operational considerations, a single well field trial, and a five well development phase evaluation project. The pilot project was performed on a horizontal, 27 stage lateral in the Aguada Pichana Oeste field in the Neuquen Basin of Argentina. The five well development phase evaluation project was performed in the Lindero Atravesado field. Positive laboratory test results led to a field trial using this technology, during which several benefits of the VFR fluid system began to emerge. Operational efficiency was an early success, including a reduction in the quantity of chemicals on location, more simplified pumping schedules, and low pumping pressures. Secondly, significant cost savings were realized compared to previous fluid system packages. Finally, positive production results were observed, leading to the decision to incorporate this technology into full field development operations. This paper will review the results of the stepwise evaluation process along with a focus on the economic benefits and well production from the development phase evaluation project. This paper describes the transition by Pan American Energy (PAE) from conventional fracturing fluids to viscosifying friction reducer (VFR) technology in the Vaca Muerta Formation. The paper highlights the performance of a relatively new treatment fluid which delivered positive results in a strategic international asset. The project has led to full field development using this technology. The same efficiencies provided by this system can potentially be realized through applications in other basins.
